Orion is an open source project under the Eclipse top-level project. The project is currently in the Incubation phase. See the original project proposal for details on the scope and goals of the project.

Orion's objective is to create a browser-based open tool integration platform which is entirely focused on developing for the web, in the web. Tools are written in JavaScript and run in the browser. Unlike other attempts at creating browser-based development tools, this is not an IDE running in a single tab. Links work and can be shared. You can open a file in a new tab. Great care has been taken to provide a web experience for development.
